Abstract

Lidar and radar are two useful tools for cirus clouds, which can provide the possibility to retrieve the vertical profiles of both the number density of particles and their microphysical characteristics, especially, when they operate together simultaneously. In this study, a multi-wavelength Lidar and a 35 Ghz Radar with polarization channels are employed to measure the properties of cirrus clouds in Hefei. The backscattering coefficient at 0.532 μm from lidar, and the effective reflectivity factor from radar are inversed for use. Furthermore, the quantities responsible for microphysics can be extracted and explained as the dimensionless values, such as the depolarization ratio and color ratio. Then these optical properties for cirrus cloud during campaigns are analyzed and compared with calculating results.
